Marie Sharp's Beware Hot Sauce is extremely hot thanks to pure Capsuim Oil and Habanero pepper mash. This hot sauce reigned as Marie Sharp's hottest until the Smokin' Marie came out and gave it some stiff competition. Although the Beware Hot Sauce contains Capsium Oil, it still delivers all the delicious, high-quality flavor that makes Marie Sharp's one of the world's most famous hot sauce brands.
